China Telecom Corp (0728.HK), the smallest of China’s three wireless operators, will invest 200 million yuan ($40 million) to build data centres in Hong Kong and Singapore, as it takes tentative steps out of its home market and diversifies its business.

The company would also look to other markets including Japan and Australia to build more data centres, Deng Xiaofeng, chief executive officer of China Telecom’s international arm told Reuters in an interview.

He said the data centre push was aimed in part at attracting more clients outside China.

“Our focus will really be on corporate clients here,” Deng said. “We’re looking for markets that are open to external investment and where there’ll be a lot of interest from our corporate clients, which is why Singapore and Hong Kong were picked.”

China Telecom competes with China Unicom (0762.HK) and China Mobile (0941.HK) in the world’s largest mobile market with more than 800 million users. Slowing growth and cut-throat competition has led to all three players looking for new revenue sources to fuel future growth.
